相对排名。题意很简单，给一个数组表示一堆运动员的名次，请输出他们的相对排名，前三名需要有一些改动。例子如下，
Input: [5, 4, 3, 2, 1] Output: ["Gold Medal", "Silver Medal", "Bronze Medal", "4", "5"] Explanation: The first three athletes got the top three highest scores, so they got "Gold Medal", "Silver Medal" and "Bronze Medal".
For the left two athletes, you just need to output their relative ranks according to their scores.
思路是先对input排序，然后对前三名做一些变动，其余名次不变。
